Description of reference numerals: USB mouse reader 1, main control chip 11, mouse 12, RFID reader 13, host computer 2.
Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
As shown in Figure 1, frame of broken lines is represented USB mouse reader 1, comprises RFID reader 13, mouse 12, main control chip 11, and main control chip 11 has the interface that is connected with RFID reader 13, mouse 12 and host computer 2.The interface that main control chip 11 is connected with mouse 12 is USB interface or serial ports.The interface that main control chip 11 is connected with RFID reader 13 is a serial ports.The interface that main control chip 11 is connected with host computer 2 is a USB interface.The control chip of RFID reader 13 and mouse 12 can be integrated in the main control chip 11, such chip controls mode of working as, and performance is more stable, and volume is littler.
Main control chip 1 is mainly finished obtaining and handling mouse 12 and RFID reader 13 data messages, receive position coordinate data on the one hand from mouse 12, receive on the one hand from RFID reader 13 electronic tag datas, these data are transferred to host computer 2 (PC etc.) via the USB interface of main control chip 1, while main control chip 1 also will be finished the USB device that powers on and enumerate, and makes host computer 2 that it is identified as HID (Human Interface Device) equipment complex like this.And mouse 12 is just finished mouse function, machinery or optical mouse all can, produce coordinate data by machinery or optical principle, main control chip 1 is by interrupting or inquiry mode obtains these data.RFID reader 13, be used to read and write electronic tag, as required, RFID reader 13 can adopt various working frequency range (for example ultrahigh frequency of the high frequency of 13.56Mhz, 915Mhz etc.), RFID reader 13 recognition data are passed to main control chip 1 by serial ports, and main control chip 1 is passed to host computer with data by USB interface or serial ports after treatment.
Those of ordinary skill in the art will appreciate that embodiment described here is in order to help reader understanding's principle of the present utility model, should to be understood that protection domain of the present utility model is not limited to such special statement and embodiment.Those of ordinary skill in the art can make various other various concrete distortion and combinations that do not break away from the utility model essence according to disclosed these technology enlightenments of the utility model, and these distortion and combination are still in protection domain of the present utility model.
